update_tag

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of disclosing behavioral traits. The description only states the action without any mention of side effects, permissions, validation rules, reversibility, or response format. For a mutating operation, this is a significant transparency gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence and is front-loaded with the core purpose. However, it is under-specified; it lacks the necessary details that would make it appropriately sized for a tool with this complexity. It is shorter than typical descriptions and sacrifices informative content for brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has five parameters, no output schema, no annotations, and the description is only one sentence, it is highly incomplete. The description fails to provide any context about parameter behaviors, return values, or use cases, leaving agents with insufficient information to correctly invoke the tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 0%, and the description does not explain any of the five parameters (name, color, tagId, projectId, description). Since the schema only lists parameter names and types, and the description adds no semantics, agents are left without guidance on how to set or interpret these parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Update an existing tag' clearly identifies the action (update) and resource (tag), and the word 'existing' implies this tool is not for creation, distinguishing it from create_tag. However, it does not elaborate on what fields can be updated or provide any additional context that would differentiate it from other update tools like update_task or update_project.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It does not mention any prerequisites, conditions for use, or situations where another tool like create_tag or delete_tag would be more appropriate. There is no explicit 'when' or 'when not to use' context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
